Verdict
The clearest difference is price: Quill at Free against pdfManager's $0.99. Quill also leads on rating (4.7 vs 4.0) and update cadence (fortnightly vs every 4 months). pdfManager's advantage is in-app purchases (none vs 1). On ads, monetization model, device support and iOS requirement there is nothing between them.
